There are way too many variables, like cast and crew requirements. There really is no "typical" any more.
The crew size depends on how much the set moves. Nothing flies in Avenue Q hence no flyman. It also had a small cast with no stars and a small orchestra and could run for a long time in the Broadway run grossing in the 200-300 range.
The play Proof was one stationary set with 4 actors on stage hence a small payroll all around and a very profitable two year run.
A big musical with some stars (like How to Succeed) has a big payroll, and great big musical (like Spiderman) has crew costs into the stratosphere.
Then there would be the way royalties (authors, director, choreographer, designers) are structured which can be all over the place.
